<p>OSSL_PROVIDER-base - OpenSSL base provider</p>

<h1 id="DESCRIPTION">DESCRIPTION</h1>

<p>The OpenSSL base provider supplies the encoding for OpenSSL&#39;s asymmetric cryptography.</p>

<h2 id="Properties">Properties</h2>

<p>The implementations in this provider specifically have this property defined:</p>

<dl>

<dt id="provider-base">&quot;provider=base&quot;</dt>
<dd>

</dd>
</dl>

<p>It may be used in a property query string with fetching functions.</p>

<p>It isn&#39;t mandatory to query for this property, except to make sure to get implementations of this provider and none other.</p>

<dl>

<dt id="type-parameters">&quot;type=parameters&quot;</dt>
<dd>

</dd>
<dt id="type-private">&quot;type=private&quot;</dt>
<dd>

</dd>
<dt id="type-public">&quot;type=public&quot;</dt>
<dd>

</dd>
</dl>

<p>These may be used in a property query string with fetching functions to select which data are to be encoded. Either the private key material, the public key material or the domain parameters can be selected.</p>

<dl>

<dt id="format-der">&quot;format=der&quot;</dt>
<dd>

</dd>
<dt id="format-pem">&quot;format=pem&quot;</dt>
<dd>

</dd>
<dt id="format-text">&quot;format=text&quot;</dt>
<dd>

</dd>
</dl>

<p>These may be used in a property query string with fetching functions to select the encoding output format. Either the DER, PEM and plaintext are currently permitted.</p>

<h1 id="OPERATIONS-AND-ALGORITHMS">OPERATIONS AND ALGORITHMS</h1>

<p>The OpenSSL base provider supports these operations and algorithms:</p>

<h2 id="Asymmetric-Key-Encoder">Asymmetric Key Encoder</h2>

<p>In addition to &quot;provider=base&quot;, some of these encoders define the property &quot;fips=yes&quot;, to allow them to be used together with the FIPS provider.</p>
